Research summaryMicrobiology of the gastrointestinal tract


Dr Bateup's research (in collaboration with Professor Gerald Tannock) has focused on lactobacilli, which are members of the normal microflora of several animal species.

One study involved the production of the enzyme bile salt hydrolase (which deconjugates conjugated bile salts in the intestinal tract resulting in deconjugated bile acids) and the enzyme's effect on bacterial growth. In another project, molecular techniques such as ribotyping were used to investigate the lactobacilli present in the gastrointestinal tract of swine.
